Challenges Reduced Time-to-Market for new service offerings Real-time AAA functionality for Subscriber and Content Provider Fraud Prevention and Revenue Assurance Support for international service offerings like t-zones or T-Mobile SoundLogo Discussing the T-Mobile Implementation (3) Challenges and Lessons learned

23. Lessons learned International management of requirements is necessary. Earlier organisational setup of international coordination would have prevented regional issues. Centralised training and first-level support for all national operators helped to prevent duplication of efforts. Establishing round tables for experience exchange helps new operators to understand the product and to prepare themselves. Discussing the T-Mobile Implementation (4) Challenges and Lessons learned

24. Future Visions The T-Mobile Implementation T-Mobile Implementation

25. Pay-anything with your telephone invoice will become one of the standard payment methods. Customers will demand for more services in real-time, like Video Streaming and Online Multiparty Gaming. Customers will demand these service wherever they are. Thus new concepts for Content Roaming are required. The Content Provider World will grow dramatically, even normal retailing companies will introduce their own Mobile Portals. Future Visions for Mobile Content Business Future Visions
